Gene

SYCP3

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

Component of the transverse filaments of synaptonemal complexes (SCS), formed between homologous chromosomes during meiotic prophase. Has an essential meiotic function in spermatogenesis. May be important for testis development. Required for efficient phosphorylation of HORMAD1 and HORMAD2 (By similarity).By similarity

Involvement in diseasei

Spermatogenic failure 4 (SPGF4)1 Publication

The disease is caused by mutations affecting the gene represented in this entry.

Disease descriptionAn infertility disorder characterized by azoospermia, a condition of having no sperm present in the ejaculate. Testicular histology shows arrest of spermatogenesis at the pachytene stage of primary spermatocytes.
